Calliope mini maze game
Introduction
This project is about programming the Calliope mini V2 in C++. See also here for the features of the device.
Although there are some very good editors for the device like the PXT from Microsoft (MakeCode) and Open Roberta Lab of Fraunhofer IAIS, Media Engineering Department (NEPO) there is also the possibility to program the device with C++.
To program with C and C++ check out https://github.com/calliope-mini and especially the following projects:
- https://github.com/calliope-mini/calliope-demo: check the source folder for examples on how to use the different components of the Calliope mini.
- https://github.com/calliope-mini/calliope-project-template: use this project to setup the environment for programming and generating the needed .hex files for the Calliope mini.
Documentation
Here you can find the documentation of the micro:bit runtime which is built on top of the ARM mbed and nordic nrf51 platforms.
Project setup
After doing the steps from the calliope-project-template, overwrite the project files with the files of this repo.
Notice that the original project template code is provided under the Apache-2.0 license.
Setup on manjaro
Yotta is available as pamac package in the AUR repositories. If yt update is done the system is compromised by many many things like python2 and rust and other things. So use the timeshift feature before.
Compiling
Inside the CMakeLists.txt file a custom target compile is setup which does yt build in the source folder.
The real reason of the CMakeLists.txt file is to enable syntax highlighting and stuff like that for the IDE.
Compiling on manjaro
The yt build will not work out of the box. Install the cross-compiler and tools from the official repositories.
Installation on the Calliope mini
The generated .hex file lands in the build/calliope-mini-classic-gcc/source/ folder and is named calliope-project-template-combined.hex. Copy this file into the mounted share MINI of the Calliope mini device connected to the PC with a USB-cable.
The game
It is about imitating the good old dungeon crawlers like The bards tale or something like that. In this version at least walking around in a "3D-view" works. The goal is to find a special place on the map. As faster the little RGB LED is pulsing as nearer the final spot is. Use the buttons A and B to turn left and right and both at the same time for stepping forwards. Also some secrets are hidden.
Concept "3D-view"
Beginning in the middle, the player is the dot in the lower middle and we can see the walls top down as little boxes.
In the upper row we can see the walls shaded if we would stand inside the floor and we would have more than 5x5 pixels on the display.
In the last row we can see the corresponding drawing as we do on the small display of the Calliope mini.
We only see one field before us and one on the left and on the right.
